Researchers have now been linking the huge disintegration of civilizations faced by many countries around 4,000 years ago to climatic change, as per a report revealed recently.

The team of researchers from Woods Hole Oceanographic Institution in Massachusetts had begun to discover massive remains of Harappan settlements along the Indus River and its tributaries. Also, they had searched for the same in the desert region at the border of India and Pakistan.

It was found by the researchers that the largest civilization, almost 10% of the world population, had once expanded itself up to more than 386,000 square miles from the Arabian Sea to the Ganges along the River.

Also, it is being said that the civilization disintegrated between 3,900 and 3,000 years ago and most people migrated towards the east. Also, mostly urban civilizations were affected.

Liviu Giosan, a geologist, and colleagues have also reconstructed the landscape of the plain and rivers wherein the development of long-forgotten civilization had taken place. "Our research provides one of the clearest examples of climate change leading to the collapse of an entire civilization", he adds.
